The modulations schemes used for LTE uplink are QPSK, 16-QAM, 64-QAM
Signals" as part of the Technical Workshop on Upstream
5% can be achieved to support 64-QAM
signals by either reducing output power or increasing supply voltage.
The SetPal technology provides for a DVB (digital video broadcasting) compliant digital terrestrial receiver that supports COFDM transmission and QPSK (quadrature phase shift keying), 16-QAM (quadrature amplitude modulation), and 64-QAM
WiMAX Forum certifiable design for CPE -- Mini-PCI design enabling compact, easy-to-use solutions -- Meets all six SUI Non Line of Sight channel models -- Adaptive modulation BPSK, QPSK, 16-QAM & 64-QAM
Advanced TDMA boosts upstream capacity by a factor of three by the use of 64-QAM
(Quadrature Amplitude Modulation) techniques and higher symbol rates.
1 bps/Hz, adaptive modulation to 64-QAM
and a cell range of 30 km, making it one of the most robust non-line-of-sight (NLOS) solutions available today.
The AIReach Broadband network is a carrier-quality multimedia service transport mechanism that uses 16- and 64-QAM
modulation with advanced power control methods to provide high capacity and low bit error ratios (BER) even under very heavy rain conditions," Corrigan said.
About 44 percent of MSOs surveyed have chosen 64-QAM
as the modulation technology for digital TV channels.
The flexible architecture also has been designed to work with 64-QAM
Users can select from QPSK, 16-QAM and 64-QAM
modulation; and can select TDMA and FDMA technologies, all of which can be supported simultaneously within a sector, thereby providing superior design flexibility to network engineers.
It transmits 43 megabits per second in a single 6-MHz cable channel, one-third more data and at lower cost than competing 64-QAM
